Memory IC Procurement Notes

Verify the specific suffix 'MA' against official datasheets to confirm the exact temperature grade and package variant, as suffixes define critical environmental and physical specifications. Ensure design compatibility with the BGA-48 footprint and 3.3V logic levels before ordering. Confirm lead times directly with the manufacturer or authorized distributors due to potential supply chain variability.

Memory IC Selection Notes

Select this part when designing systems that require non-volatile memory with infinite endurance and SRAM-like speed. The 128k x 16 organization suits applications needing moderate density with wide data paths. Consider the -40°C to +105°C industrial temperature range for robustness. Verify that the parallel interface fits the target microcontroller's available pins and timing constraints.
